Appendix B: Troubleshooting
T1. How do I restore my Range Extender’s configuration to its factory default settings?
There are TWO methods available to restore the factory defaults.
Method 1:
With the Range Extender RE210 powered on, press the Reset button on the side panel for 5 seconds before releasing it.
Method 2:
Get logged in to the web-based management page of RE210, then go to “System Tools ->
Factory Defaults” and click “Restore”.
Note:Once the Range Extender is reset, the current configuration settings will be lost and you will need to reconfigure it.
T2. What can I do if I forget my password?
1) Restore the Range Extender’s configuration to its factory default settings. If you don’t know how to do that, please refer to previous T1;
2) Use the default user name and password: admin, admin;
3) Try to reconfigure your Range Extender by following the instructions of this UG.
T3. What can I do if I cannot access the web-based configuration page?
1) Check to verify all the connections (either wireless or wired ones) are proper. If yes, please proceed to the next step; otherwise, check the connections again.
2) Try to obtain an IP address and gateway; if succeed, open your web-browser, enter the default domain http://tplinkrepeater.net in the address field and get logged in.
If you are unable to log in, please Reset the device, and then use the default IP address to get into the web-based configuration page, reconfigure the device.
3) Feel free to contact our technical support, if the problem still persists.
T4. How can I know that my wireless signal has been repeated and boosted by RE210?
An easy way is to compare the signal strength of your target wireless network (symbolized by its SSID), with RE210 in operation vs. out of operation. Before comparison, you’d better make sure your computer can obtain an IP address from your target wireless network and thus access the Internet, either via RE210 or without.
T5. Will the Range Extender work if I connect the Ethernet port of it to the router via Ethernet cable?
Sorry, it won’t work. The Range Extender is designed to connect wirelessly to the router, while the Ethernet port is designed to connect with a wired device, like Internet TV, Gaming console, DVR and so on.
T6. Why does the wireless transmission rate speed down, while the wireless signal is stronger after repeated by RE210?
In compliance with the wireless transmission protocol, all the Range Extender devices are set to work in half-duplex instead of full-duplex mode. In other words, the Range Extender has to process one-way communication between your root Wireless Router or AP and the terminal clients; so the transmission time will be double-increased, while the speed will be decreased.
TP-LINK recommends that you connect to the Range Extender when your home network connection is poor, or when you want a larger wireless coverage to eliminate “dead zones”.

Appendix D: Glossary
802.11ac - IEEE 802.11ac is a wireless computer networking standard of 802.11.This specification will enable multi-station WLAN throughput of at least 1 gigabit per second .This is accomplished by extending the air interface concepts embraced by 802.11n: wider RF bandwidth, more MIMO spatial streams, multi-user MIMO, and high-density modulation (up to 256 QAM).
802.11n - 802.11n builds upon previous 802.11 standards by adding MIMO (multiple-input multiple-output). MIMO uses multiple transmitter and receiver antennas to allow for increased data throughput via spatial multiplexing and increased range by exploiting the spatial diversity, perhaps through coding schemes like Alamouti coding. The Enhanced Wireless Consortium (EWC) was formed to help accelerate the IEEE 802.11n development process and promote a technology specification for interoperability of next-generation wireless local area networking (WLAN) products.
802.11b - The 802.11b standard specifies a wireless networking at 11 Mbps using direct-sequence spread-spectrum (DSSS) technology and operating in the unlicensed radio spectrum at 2.4GHz, and WEP encryption for security. 802.11b networks are also referred to as Wi-Fi networks.
802.11g - specification for wireless networking at 54 Mbps using direct-sequence spread-spectrum (DSSS) technology, using OFDM modulation and operating in the unlicensed radio spectrum at 2.4GHz, and backward compatibility with IEEE 802.11b devices, and WEP encryption for security.
Access Point (Range Extender) - A wireless LAN transceiver or "base station" that can connect a wired LAN to one or many wireless devices. Access points can also bridge to each other.
DNS (Domain Name System) – An Internet Service that translates the names of websites into IP addresses.
Domain Name - A descriptive name for an address or group of addresses on the Internet.
DoS (Denial of Service) - A hacker attack designed to prevent your computer or network from operating or communicating.
DSL (Digital Subscriber Line) - A technology that allows data to be sent or received over existing traditional phone lines.
ISP (Internet Service Provider) - A company that provides access to the Internet.
MTU (Maximum Transmission Unit) - The size in bytes of the largest packet that can be transmitted.
SSID - A Service Set Identification is a thirty-two character (maximum) alphanumeric key identifying a wireless local area network. For the wireless devices in a network to communicate with each other, all devices must be configured with the same SSID. This is typically the configuration parameter for a wireless PC card. It corresponds to the ESSID in the wireless Access Point and to the wireless network name.
WEP (Wired Equivalent Privacy) - A data privacy mechanism based on a 64-bit or 128-bit or 152-bit shared key algorithm, as described in the IEEE 802.11 standard.
Wi-Fi –A trademark of the Wi-Fi Alliance and the brand name for products using the IEEE 802.11 family of standards.
WLAN (Wireless Local Area Network) - A group of computers and associated devices communicate with each other wirelessly, which network serving users are limited in a local area.
WPA (Wi-Fi Protected Access) - WPA is a security technology for wireless networks that improves on the authentication and encryption features of WEP (Wired Equivalent Privacy). In fact, WPA was developed by the networking industry in response to the shortcomings of WEP.
One of the key technologies behind WPA is the Temporal Key Integrity Protocol (TKIP). TKIP addresses the encryption weaknesses of WEP. Another key component of WPA is built-in authentication that WEP does not offer. With this feature, WPA provides roughly comparable security to VPN tunneling with WEP, with the benefit of easier administration and use. This is similar to 802.1x support and requires a RADIUS server in order to implement. The Wi-Fi Alliance will call this, WPA-Enterprise. One variation of WPA is called WPA Pre Shared Key or WPA-Personal for short - this provides an authentication alternative to an expensive RADIUS server. WPA-Personal is a simplified but still powerful form of WPA most suitable for home Wi-Fi networking. To use WPA-Personal, a person sets a static key or "passphrase" as with WEP. But, using TKIP, WPA-Personal automatically changes the keys at a preset time interval, making it much more difficult for hackers to find and exploit them. The Wi-Fi Alliance will call this, WPA-Personal.
